NW Conversions 28 Gallon Wheel Well Water Tank - Promaster (Driver Side)

28 Gallon Promaster Water Tank (Driver Side / Left Offset)

Designed for Promaster Driver Side Conversions

Maximize the functionality of your van’s layout with this 28-gallon wheel well water tank, specifically designed for the Driver’s Side (Left) of the Ram Promaster. Unlike centered tanks, this unit features an offset design, positioning the water storage to the left of the wheel well (extending towards the rear of the van) to accommodate specific floor plans and cabinetry layouts.

While engineered for the Promaster, this tank can also be utilized in Ford Transit and Mercedes Sprinter builds where a driver-side offset fit is required (insulation gaps may vary).

Made in the USA from durable, BPA-free food-grade plastic, this tank is tough enough for off-grid adventures. It features the same versatile port configuration as our centered models, allowing for easy venting, filling, and sensor installation.

Key Features:

• Driver Side Offset: Designed to sit over the wheel well with the bulk of the capacity extended to the left (rearward) side, ideal for driver-side galleys or bed systems.

• Space Efficient: Hugs the wall and wheel housing to keep your center of gravity low and save interior space.

• Safe & Certified: Rotomolded from BPA Free Food Grade Plastic ensuring safe fresh water storage.

• Versatile Plumbing:

  • (2) 1/2” NPT ports (open and ready to use).

  • (2) 1.5” NPT ports on ends (Note: Spun closed, must be drilled if used).

  • (1) 1.5” NPT top port (Note: Spun closed, needs drilling) for gravity fill or level sensors.

• Made in the USA: Built to last with heavy-duty construction.

• Ram Promaster: Optimized for the Driver’s Side wheel well.

• Mercedes Sprinter & Ford Transit: Compatible with the driver’s side wheel well (additional gap may exist at the top due to smaller wheel wells in these models).
